Contractions are heating up

Debra is having bigger contractions now and about once every 4 minutes, although less often when she's lying down.
Its been 6 hours now since her water was broken and she is now at a 4 and 85 % effaced. Now she has to dilate at least a cm an hour, so the doctor is starting her on pitocin (sp?). We tried to avoid it as long as possible but she wasn't progressing fast enough.
The good news is that it is almost certain that doctor Newell will be able to deliver him now. She goes on call at 5 pm.
Debra seems to be doing really well. When we were walking, she was the one voting for just one more lap. She's reading a Jan Karon novel right now which is helpful in taking her mind off the pain. Gram was the one who originally introduced Debra to Karon as a tasteful writer.
Well, with the pitocin started, things should speed up a little now. We'll let you know what happens.
